The 400G QSFP-DD is designed to be compliant with the IEEE 802.3bs 400GBASE-LR8/FR8 and QSFP-DD MSA specifications for links up to 10km. The 400G CFP8 FR8/LR8 is designed to be compliant with the IEEE 802.3bs 400GBASE-LR8/FR8 and CFP MSA specifications for links up to 10km.

“We are proving to the market that multiple 400G offerings will be available in the short term to support connectivity between transport, routing and switching equipment,” says Ed Ulrichs, director of PLM. “Operators can now believe a strong foundation exists to plan network upgrades,” he adds. “Both of these transceivers will be available for customer samples in early second-quarter 2018.”

Source Photonics is demonstrating an error-free link between its 400G QSFP-DD LR8 and 400G CFP8 LR8 at the Optical Networking and Communication Conference & Exhibition (OFC 2018) in San Diego (13-15 March), proving that links up to 10km can soon upgrade from 100G to 400G, therefore significantly reducing total cost of ownership in the aggregation layer.

“We have successfully integrated our industry-leading signal integrity work with novel optical coupling concepts to demonstrate the highest-density optical transceiver ever,” claims chief scientist Sheng Zhang. “Since we use a common manufacturing platform with our 100G products, we are confident we will be the first in the market to scale this platform,” he adds.
